iSCSI Initiator Settings
Network Configuration
1. Create a single vSwitch with the NICs you want to use for iSCSI and set them as "Unused Adapters" in the NIC Teaming tab.
2. Create a "vmkernel" for each NIC and override the Teaming Settings, moving only a single NIC to "Active Adapters for each ".
3. Now that we have a properly configured vSwitch, we can bind the vmkernels to the iSCSI Initiator.
